Disclosed is an enclosed type compressor in which a scroll type compression mechanism and an electric motor are attached firmly to a casing, with the scroll type compression mechanism and the electric motor in contact with an inner face of the casing. Formed in a plane orthogonal to the longitudinal direction of the casing are a contact part of the casing which makes contact with the scroll type compression mechanism (the electric motor) and a non-contact part of the casing which does not make contact with the scroll type compression mechanism (the electric motor). The non-contact part with respect to the scroll type compression mechanism has a peripheral length different from that of the non-contact part with respect to the electric motor.
